I know most of us with original R12 systems are using the propane/butane blends (duracool etc) and that's working just fine.

In my case, the coach system was changed to use R134A and with that refrigerant becoming harder to source (Canada - Montreal protocol) I'm leaning towards installing R152A - 1,1 Diflouroethane CAC 75-37-6, a refrigerant commonly sold as "compressed air" or "duster".

Apparently this is totally compatible with the seals and PAG oils found in R134A systems, has better cooling properties and needs far less by weight to fill a system. The quantity of R152A in an R134A system is determined by using the formula (oz.R134A x 0.64) = oz.R152A.

I haven't tried it in my TZE (yet) but I've got a 2003 Ford Explorer that blows warm. That system calls for 32oz of R134A so it'd take 20.4oz R152A ..so basically I can fill it if I pick up a 12oz and a 10oz can of duster. Planning to do so soon.

R152A can be used in an R12 setup too, but I believe the systems have to be drained of the old oil and replaced with PAG, just as you would if you were converting to R134A.

The reason I started looking at R152A again (first heard about it about 12 yrs ago) is because my shipment of 12 cans of R134A that I just bought on eBay got stopped at the Global Shipping depot and tagged "undeliverable" due to some green BS regulation. So they refunded me. I've re-ordered some more on Amazon; maybe that will arrive.

Life is full of workarounds for do-it-yourselfers driving old things eh? Rolling Eyes
